Answer: x= 3
Step-by-step explanation:
2x + 5 = 11
2x = 6
x = 3
Answer:
1.) 9.2
2.)
625
633
the dealer
8.81
Step-by-step explanation:
I'm gonna assume that cm= compounded monthly
1.)
effective rate: .153/12= .01275
x= payments
![2590.67=300*\frac{1-(1+.01275)^{-x}}{.01275}\\.110103476=1-1.01275^{-x}\\.889896525=1.01275^{-x}\\\log_{1.01275}.889896525=-x\\x=9.207](https://tex.z-dn.net/?f=2590.67%3D300%2A%5Cfrac%7B1-%281%2B.01275%29%5E%7B-x%7D%7D%7B.01275%7D%5C%5C.110103476%3D1-1.01275%5E%7B-x%7D%5C%5C.889896525%3D1.01275%5E%7B-x%7D%5C%5C%5Clog_%7B1.01275%7D.889896525%3D-x%5C%5Cx%3D9.207)
2.)
If there is no interest rate attached to financing through the deal the payment is just
37500/60 = 625
The monthly payment from the bank has a present value of 37500-3000=34500
and the effective rate is .039/12= .00325
![34500=x\frac{1-(1.00325)^{-60}}{.00325}\\34500=54.43234738x\\x=633.81](https://tex.z-dn.net/?f=34500%3Dx%5Cfrac%7B1-%281.00325%29%5E%7B-60%7D%7D%7B.00325%7D%5C%5C34500%3D54.43234738x%5C%5Cx%3D633.81)
Finally, the amount we save is just the difference
633.81-625=8.81
Slope: 3, y-intercept: 4, equation: y = 3x + 4
